SUPPORT FOR RAILWAY MOTOR-CABLES.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, FRANK W. GARRETT, a citizen of the United States,residing at Nor- Wood, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Supports for RailwayMotor-Cables, of which the following is a full, clear, and exactspecification.

My invention relates to electric railwaycar equipment, and particularlyto the means for supporting the cables leading from the car-motors.

At the present time it is customary in electric-railway work, especiallyon interurban roads, to employ cars having bogie or swiveled trucks withone or more motors mounted thereon. To permit proper play of the truckson curves and switches, it has been heretofore considered necessary toallow a considerable length of cable between the carbody and the motorsand to permit said cable to hang freely in long loops. This slack in thecable-leads to the motor is very objectionable, because there is greatliability of said leads becoming damaged by striking against or beingcaught between the moving parts. Any material damage to these leadscripples the car, or at least part of its equipment.

The object of my invention is to reduce the liability of accident anddamage to the electrical equipment of the car by supporting in a simpleand eflicient manner said cableleads on the truck or motor as nearly aspossible in vertical alinement with the king-bolt or center of thetruck. This arrangement materially reduces the length of free cablenecessary to permit proper play of the truck relative to the car.

In carrying out my invention'I employ a support for the cables, as acable-cleat, which is fastened to the motor-casing or to the truck-framepreferably approximately in vertical alinement with the kingbolt of thetruck and to construct said cleat in such a manner that the cables maybe readily removed therefrom. The cleat is also preferably constructedso that the cable or cables which lead to the lower half of themotor-casing may be re moved from the cleat without disturbing theremaining cables in said cleat. Such a construction permits themotor-casing to be opened and the lower half to be swung away withoutunnecessary delay in disconnecting taped joints or in cutting leads.

in the accompanying drawings, which illustrate the preferred embodimentof the invention, Figure 1 is a diagrammatic view in elevation of amotor-truck looking from the center thereof, showing the cable-leadssupported in accordance with my invention. Fig. 2 is a diagrammatic planview of a bogietruck, showing the preferred arrangement ofcable-supports relative to the truck center. Fig. 3 is a plan view ofpart of the motor shown in Fig. 1. Fig. 4 is a side view of thecable-cleat, showing the preferred manner of attaching same tomotor-casing. Fig. 5 is an end elevation of the cleat, showing amodified form of attaching means; and Fig. 6is a plan view of the cleat.

Referring now to the drawings, the motor A is shown as divided, so thatthe lower half 7 can be removed from or swung downward on the upper half8. The motor is inounted in the customary manner in the truckframe B.The eable-leads from the fieldcoils and armature of the motor are shownat 9, 10, 11, 12, and 13. These cables leave the motor-casing atdifferent points, and their terminals are fa stened to the terminal boxD, carried by the bolster O, which forms part of the car-body. It hasbeen customary to permit these cable-leads to hang loosely between theterminal box and the points of egress from the motorcasing. This led tonumerous difficulties and considerable damage to the electricalequipment of the car, due to said leads getting caught on or rubbingagainst moving parts of the truck or motorcasing. To avoid suchdifficulties and damage, 1 support the cable-leads in the cleat 15,mounte d on the motor-casing or the car-truck, (here shown as mounted onthe casing,) as nearly as possible in vertical alinement with theking-pin K, or center of the truck. This cleat is formed of two parts ofwood or other insulating material 16 and 17 which are fastened togetherand to the motor-casing by means of the screws 18, as clearly shown inFig. l. The parts 16 and 17 are grooved to receive the cables 9, 10, 11,and 12, which lead from the upper half of the motor-casing. The upperpart 16 of said cleat is also grooved to receive the cable 13, whichleads from the lower half of the motor-casing. This latter or otherwiseremoved from the upper half cable must be disconnected from car-bodywhen it is desired to remove the lower half of the motor for the purposeof inspecting the armature or for any other reason. To t'acilitate theremoval of this lead from the cleat 15 without interfering with thesupport for the remaining leads, I provide a pivoted catchplate 19. Thiscatch-plate is pivoted at one end on the screw 20 and is provided withthe slotted portion 22, which permits the opposite end of said plate totake under the heail of screw 21, and thus hold cable 13 in its groove.Then it becomes necessary to remove the lower half of the motor-casing,the cable 13 is removed from the cleat 15 by swinging plate 19 to onesi'le, it being clear that said cable is readily removable from theterminal box D.

A modified form of support for the cleat 15 is shown in Fig. 5, saidcleat being mounted upon a piece of sheet metal 24, bent into the shapeshown in said figure, one end being clamped under the nut 23 on the bolt26, which holds one of the motor pole-pieces in position, the upper endbeing fastened to the cleat between the extra strip 25 and the lowerpart 17.

I aim in the appended claims to cover all modifications and changes inthe construction and arrangement of my improved cable-.

support which do not involve a departure from its spirit and scope.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In combination, a car-body, a cartrrclt adapted to ttrn relative tosaid body, a motor on said truck, cable-leads between the motor and thecar-body, and a support for said cable-leads movable with said trrol:and located approximately in vertical alinement with the king-pin of thetruck.

2. In combination, a car-body, a cartruck adapted to tiirn relative tosaid. body, a motor 011 said truck, cableleads between the motor andcar-body, and a cleat movable with said tT'tICli for supporting thecable-lead. I

intermediate their ends.

3. In combination, a car-body, a cartruck adapted to tern relative tosaid body, a motor supported on said truck, cable-leads between themotor and the car-body, and

means on said motor for supporting the cables intermediate their ends.

4. In combination, a car-body, a cartruck adapted to turn relative tosaid body, a motor supported on said truck, cableleads between the motorand the oar-body, and a support on the motor for the cables intermediatetheir ends, flexible portions of the latter being between the supportand the car-body.

5. In combination, a car-body, a cartriick adapted to turn relative tosaid body, a motor 0:1 said trrck, cable-leads between the motor andcar-body, and. a cleat movable with said trr ck for siipportiiig thecableleads intermediate their ends, and means whereby ore of saidcable-leads may be removed from the cleat withoit interfering with theremainiitg leads supported by said cleat.

6. In combiz'iation, a oar-body, a cartrrck adapted to trrn relative tosaid body, a motor on said trrck, cable-lads between the motor andcar-body, and a cleat movable with said trrck for siipporting thecableleads intermediate their ends, and mears lor Fasten .g ore of saidleads to the cleat inde- 1-... i 1 .1 1 pence-.t of the remamoer oi tneleans so that said lead may be removezil therefrom withort interferingwith the remai: ler of the leads.
